I have about 81,000 miles on my car and I'm running Valvoline Durablend 5W 30 (a syntheticly blended oil). I have heard that after about 75,000 miles it's a good idea to switch to an oil like Valvolines Max Life to help restore and protect the engine. Do you think there is any advantage to one of these "higher milage oils" or no? 
You may want to check out my Group Buy on extended drain interval synthetics for some hints on oil change intervals.
